Dunno if any of you all have run across this at some points, but it's a flash MMO based from the guys that made AdventureQuest, Dragon Fable, MechQuest. Adventurequest Worlds (AQW) is not something that'll totally immerse you, but it's something interesting to pass the time when you're bored with whatever the latest craze is, or at some public place where you can't get into a hardcore game (airport layoversssss).
There's a good amount of internet humor in it, and they update the game every week, ranging from small updates such as inventory expansion to a new zone. It has an ongoing story that actually develops, and it at minimum you can play maybe 30 minutes to an hour a week and still keep up with the game.
So if you're bored, or might want to have an alternative that you could play with someone who's not as hardcore as us, lol, try out AQW. There is a pay-to-play option that gives you access to the members server, but you can join your own version of the zones by joining a high-level.
Example, typing /join <zone name>-23432 will put you into a private zone, so to speak.

Name is Pathfinder in-game if you guys try it out. They tweak the game a lot, so it might feel unbalanced right now. PvP is slated, but on the drawing board, as well as guilds.
